However, few strategies can achieve a robust antifouling coating on a surface in an easy and reliable way, regardless of material type, morphology, and shape. Herein, the preparation of an antifouling coating by one-step aqueous supramolecular assembly of bovine serum albumin (BSA) is reported. Based on fast amyloid-like protein aggregation through the rapid reduction of the intramolecular disulfide bonds of BSA by tris(2-carboxyethyl)phosphine, a dense proteinaceous nanofilm with controllable thickness (?130 nm) can be covered on virtually arbitrary material surfaces in tens of minutes by a simple dipping or spraying. The nanofilm shows strong stability and adhesion with the underlying substrate, exhibiting excellent resistance to the nonspecific adsorption of a broad-spectrum of contaminants including proteins, serum, cell lysate, cells, and microbes, etc. In vitro and in vivo experiments show that the nanofilm can prevent the adhesion of microorganisms and the formation of biofilm. Compared with native BSA, the proteinaceous nanofilm coating exposes a variety of functional groups on the surface, which have more-stable adhesion with the surface and can maintain the antifouling in harsh conditions including under ultrasound, surfactants, organic solvents, and enzymatic digestion. © 2020 WILEY-VCH Verlag GmbH &amp; Co.

In this work, a highly efficient metal-free catalyst is developed by introducing F atoms into a 3D porous carbon framework (F-doped carbon) toward N2 electroreduction. At -0.2 V versus reversible hydrogen electrode (RHE), the F-doped carbon achieves the highest FE of 54.8% for NH3 , which is 3.0 times as high as that (18.3%) of pristine carbon frameworks. Notably, at -0.3 V versus RHE, the yield rate of F-doped carbon for NH3 reaches 197.7 ?gNH3 mg-1 cat. h-1 . Such a value is more than one order of magnitude higher than those of other metal-free electrocatalysts under the near-ambient conditions for NH3 product to date. https://www.selleckchem.com/products/ab928.html Mechanistic studies reveal that the improved performance in N2 electroreduction for F-doped carbon originates from the enhanced binding strength of N2 and the facilitated dissociation of N2 into *N2 H. F bonding to C atom creates a Lewis acid site due to the different electronegativity between the F and C atoms. As such, the repulsive interaction between the Lewis acid site and proton H suppresses the activity of H2 evolution reaction, thus enhancing the selectivity of N2 electroreduction into NH3 . © 2020 WILEY-VCH Verlag GmbH &amp; Co.

METHODS Among the 855 tumors of patients who underwent partial/radical nephrectomy or renal biopsy for presumed renal cell carcinoma between 2007 and 2018, 39 renal tumors were diagnosed as nonclassical angiomyolipoma, including epithelioid angiomyolipoma and fat-poor angiomyolipoma. We retrospectively evaluated the incidence of epithelioid angiomyolipoma. Furthermore, we analyzed computed tomography and magnetic resonance imaging results, including diffusion-weighted magnetic resonance imaging findings of epithelioid angiomyolipoma and fat-poor angiomyolipoma. RESULTS The incidence of epithelioid angiomyolipoma (n&nbsp;=&nbsp;7) was 17.9% of surgically resected non-classical angiomyolipoma. The radiological appearance of epithelioid angiomyolipoma was hyperattenuating on unenhanced computed tomography images with iso or low intensity on T2-weighted magnetic resonance imaging. The mean apparent diffusion coefficient value of the solid component in epithelioid angiomyolipoma was significantly lower than that in fat-poor angiomyolipoma (median 0.79&nbsp;×&nbsp;10-3 vs 1.07&nbsp;×&nbsp;10-3 mm2 /s, P&nbsp;=&nbsp;0.0019). CONCLUSIONS The proportion of epithelioid angiomyolipoma in our Japanese cohort was equivalent to that of the reported series in the USA. The apparent diffusion coefficient value is potentially useful to differentiate between epithelioid angiomyolipoma and fat-poor angiomyolipoma. Further research is required to establish the imaging diagnostic criteria for epithelioid angiomyolipoma. © 2020 The Japanese Urological Association.Aberrant epigenetic reprogramming is one of the major barriers for somatic cell reprogramming. Although our previous study has indicated that H3K27me3 demethylase KDM6A can improve the nuclear reprogramming efficiency, the mechanism remains unclear. In this study, we demonstrate that the overexpression of Kdm6a may improve induced pluripotent stem cell (iPSC) reprogramming efficiency in a demethylase enzymatic activity-dependent manner. KDM6A erased H3K27me3 on pluripotency- and metabolism-related genes, and consequently facilitated changing the gene expression profile and metabolic pattern to an intermediate state. Furthermore, KDM6A may promote IL-6 expression, and the secreted IL-6 may further improve iPSC reprogramming efficiency. In addition, KDM6A may promote PTEN expression to decrease p-AKT and p-mTOR levels, which in turn facilitates reprogramming. Overall, our results reveal that KDM6A may promote iPSC reprogramming efficiency by accelerating changes in the gene expression profile and the metabolic pattern in a demethylation-activity-dependent manner. These results may provide an insight into the relationship between epigenomics, transcriptomics, metabolomics, and reprogramming. ©AlphaMed Press 2020.The assembling behaviors of nonchiral dicationic amphiphilic molecules (gemini) in the presence of the mixture of chiral anionic nucleotides and nonchiral anions are investigated. We demonstrate that subtle balance of various physico-chemical parameters and the competition between chiral and nonchiral anions at the interface of gemini assemblies influences the expression of molecular chirality at the micrometer scale through the hierarchical molecular assembly. © 2020 Wiley Periodicals LLC.
